A 'bad' O2 sensor will not blow fuses, the heater goes open circuit. Your wiring can blow fuses.
Look for damage to the loom alongside the engine mount and exhaust mount.
Use the right O2 do not use a generic and always replace both sensors if it has a V6. If you don't do the above you will likely get another error code I know this from years of experience on this type of job.

Yeah, you could do that. Bank 1 is always the engine side where the number 1 cylinder is located. Sensor 1 is the first sensor in the exhaust system, nearest the engine. Sensor 2 is always located farther downstream in the exhaust.
